Abstract: A first device of a Multimedia Over Coax Alliance (MoCA) network may communicate with a second device of the MoCA network to control power-save operation of the second MoCA device. The first device may control the power-save operation of the second MoCA device based on an amount of data stored in a buffer, wherein the data stored in the buffer is destined for the second device. The buffer may be in a third device which sends the data to the second device, and/or the buffer may be in the first device. The first device may be operable to buffer data destined for the second device while the second device is in a power-saving state.

Abstract: A cable modem termination system (CMTS) may determine, for a plurality of cable modems served by the CMTS, a corresponding plurality of SNR-related metrics. The CMTS may assigning the modems among a plurality of service groups based on the SNR-related metrics. For any one of the modems, the CMTS may configure physical layer communication parameters to be used by the one of the modems based on a SNR-related metric of a service group to which the one of the modems is assigned. The physical layer communication parameters may include one or more of: transmit power, receive sensitivity, timeslot duration, modulation type, modulation order, forward error correction (FEC) type, and FEC code rate. The CMTS and the modems may communicate using orthogonal frequency division multiplexing (OFDM) over a plurality of subcarriers, and the physical layer communication parameters may be determined on a per-subcarrier basis.

Abstract: In an example implementation of this disclosure, a message passing low density parity check (LDPC) decoder may, during decoding of a first group of bits, lock a first variable node upon a bit-value probability of the first variable node reaching a determined threshold, and lock a first check node upon all variable nodes connected to the first check node being locked. The LDPC decoder may cease decoding the first group of bits upon all variable nodes of the LDPC decoder being locked, all check nodes of the LDPC decoder being locked, reaching a maximum number of iterations, or reaching a timeout. During a particular iteration of the decoding of the first group of bits in which the first variable node is locked, the LDPC decoder may refrain from generating a bit-value probability for the locked first variable node.

Abstract: One or more circuits for use in a transceiver that is collocated with a satellite dish, may receive a satellite signal carrying media content, and remove content protection from the received media content. After removing the first content protection, the one or more circuits may apply second content protection to the media content. The content protection applied by the one or more circuits may adhere to a different protocol, utilize different keys, and/or otherwise be distinguishable from the content protection that was removed. After applying the content protection, the one or more circuits may transmit the media content onto one or more links between the satellite dish and one or more client devices. The removal of the content protection may comprise descrambling and/or decrypting the media content. The application of the content protection may comprise scrambling and/or encrypting the media content.

Abstract: Methods and systems are provided for using decision feedback phase error correction during signal processing. When an input signal comprises a plurality of sub-carriers, each of the plurality of sub-carriers may be processed separately, for each one of the plurality sub-carriers error related information may be determined separately, based on the processing of that sub-carrier. Subsequent processing of at least one of the plurality of sub-carriers may then be adjusted based on determined error related information corresponding to one or more sub-carriers. In this regard, the subsequent processing of the at least one sub-carrier may be adjusted based on determined error related information for that sub-carrier, based on determined error related information for at least one other sub-carrier, or based on determined error related information corresponding to all of the sub-carriers. The error related information may comprise phase error related information.

Abstract: A wireless communication device generates and transmits wireless broadband signals at a power level that is below a spurious emissions mask such that the transmitted wireless broadband signals occupy a designated frequency spectrum band. A bandwidth of the wireless broadband signals may occupy approximately 800 MHz within a range of 0 Hz to 1 GHz. The transmit power utilized for transmitting the wireless broadband signals may be spread over a bandwidth of approximately 300 MHz within the 800 MHz bandwidth. The spreading results in a power spectral density of the transmitted wireless broadband signals approximating thermal noise at a distance of approximately 3 meters. Available channels within the designated frequency spectrum band may be sensed for the transmission of the wireless broadband signals. A plurality of the sensed available channels may be aggregated for the transmission of the wireless broadband signals.

Abstract: An array based communications system may comprise a plurality of element processors. Each element processor may comprise a combining circuit, a crest factor circuit, and a phase shifter circuit. The combining circuit may produce a weighted sum of a plurality of digital datastreams. The crest factor circuit may be operable to determine whether the weighted sum has a power above or below a power threshold. If the power is above the power threshold, the crest factor circuit is operable to reduce the power. If the power is below the power threshold, the crest factor circuit is operable to increase the power. The phase shifter circuit may introduce a phase shift to out-of-band components of the weighted sum according to the power increase or the power decrease by the crest factor circuit.
